We consider a model with a Majorana dark matter particle, \(\chi \) , and two scalar fields, \(\phi _q\)  and \(\phi _l\) , where the scalar field \(\phi _q\)  has a colour charge [1]}. This is a modified version of model considered in [2]}, where the fermionic dark matter field was accompanied by a scalar and a coloured fermion.
In this model, the interaction between the new particles and the SM are described by the following Lagrangian
\(\mathcal {L} = \lambda _{Q_i}\bar{Q}_{i}\phi _{q}P_{R}\chi + \lambda _{L_i}\bar{L}_{i}\phi _{l}P_{R}\chi + \rm {h.c.} \, .\)
